This file contains data from the Saildrone Inc. Uncrewed Surface Vehicle (USV) (i.e., "saildrone") core MetOcean sensors for the NOAA Pacific Marine Environmental Laboratory (PMEL) Tropical Pacific Observing System (TPOS) 2024 Mission (Mission 7) to the central tropical Pacific. The mission started on Oct 30, 2024 with a transect along the 125°W meridian from 10°N to 6°N, where the USVs then caught favorable currents to intercept the National Science Foundation (NSF)-funded Mixing belOw Tropical Instability waVEs (MOTIVE) cruise near 1°N 138°W. The MOTIVE cruise featured a drifting array of University of Washington (UW) Applied Physics Laboratory (APL) Wirewalkers and a UW profiling glider (glider PI: Katie Kohlman (UW School of Oceanography)), against which the Saildrones conducted a coordinated frontal study (Nov 22 - 26, 2024). For more information on the MOTIVE cruise, see https://www.polarsteps.com/AnnaAndTheWater/14669345-motive-cruise-i. An upwelling experiment and Tropical Atmosphere/Ocean (TAO) intercomparison at 0°N 140°W was also performed (Dec 2 - 5) before the drones were swept westward by stronger-than-usual equatorial currents associated with the La Niña. Additional scientific objectives accomplished included observations of convective cold pool events, sharp fronts of submeso- and meso-scale processes within Tropical Instability Waves, and a return to the 140°W meridian leveraging North Equatorial Countercurrent (NECC) under the Inter-Tropical Convergence Zone (ITCZ). This mission was supported through the NOAA OMAO Uncrewed Systems Operation Center (UxSOC) funded project titled "Uncrewed Surface Vehicles (USV) integrated within the Tropical Pacific Observing System", which follows the implementation strategy laid out by the Uncrewed Marine Systems (UMS) 2022 "Research to Operations - Component Service Transition Plan Volume 1-C". The PIs and mission managers were Dr. Meghan Cronin (NOAA PMEL), Dr. Dongxiao Zhang (UW Cooperative Institute for Climate, Ocean, and Ecosystem Studies (UW CICOES)), Dr. Yolande Serra (UW CICOES), and Dr. Elizabeth McGeorge (UW CICOES). Other PIs for this mission include: Dr. Adrienne Sutton (NOAA PMEL) for ASVCO2 measurements, Eugene Burger (NOAA PMEL) for data stream issues, Dr. Réka Domokos (NOAA National Marine Fisheries Service (NMFS) Pacific Islands Fisheries Science Center (PIFSC)) for fisheries applications (note: there was no EK80 deployed during this mission), Ian Sears and Stephanie Ray (both at NOAA National Data Buoy Center (NDBC)) for coordination with NDBC TPOS components, and Drs. Arun Kumar and Jieshun Zhu (both at NOAA National Centers for Environmental Prediction (NCEP)) for operational weather, climate and ocean applications. In addition to being part of the mission management team, Mr. Nathan Anderson worked with Ms. Ellen Koukel (both of UW CICOES) on the metadata creation and data archiving. The PMEL TPOS 2024 Mission (aka Mission 7) had two Saildrones: SD1033 and SD1090. Both were standard Gen 6 drones with the core MetOcean package and an ASVCO2 Gen2 carbon flux system. Both were equipped with Acoustic Doppler Current Profilers (ADCPs) at 1.86m (not included in this file). The core Conductivity, Temperature, Depth (CTD) sensor was an SBE 37-SMP at 1.7m, and a temperature logger RBR Coda^3 T at 0.5m, with 3x PMEL-provided self-logging SBE56 Temperature sensors nominally located at 0.33m, 0.75m, and 1.03m. All drones had a PMEL-provided SPN1 shielded shortwave radiometer and a Kipp and Zonen longwave radiometer (on a standalone data logger and processed separately). Carbon system data (including the CTD data) are also served through a separate file. The vehicles for the 2024 mission were deployed out of Alameda, CA, arriving on station (10°N 125°W) to initiate the mission on 30 Oct 2024. The 98-day mission was terminated 4 Feb 2025 after anemometers failed on both SD1090 (Jan 15) and SD1033 (Jan 18). If you use these Saildrone Tropical Pacific Observing System (TPOS) mission data in publications or presentations, please acknowledge the Ocean Climate Station (OCS) Project Office of NOAA/PMEL. Also, we would appreciate receiving a preprint and/or reprint of publications utilizing the data for inclusion in our bibliography. Relevant publications should be sent to: OCS Project Office at NOAA/PMEL/OCRD, 7600 Sand Point Way NE, Seattle, WA 98115 or emailed to: pmel.ocs@noaa.gov. For ASVCO2 data use, please also acknowledge the Moored Carbon and the Engineering Project Office of NOAA/PMEL, and also send ASVCO2 relevant publications to: Moored Carbon Project Office, NOAA/PMEL/OCRD, 7600 Sand Point Way NE, Seattle, WA 98115 or emailed to: adrienne.sutton@noaa.gov. In all publications, please introduce the platform as a Saildrone, Inc. Explorer Uncrewed Surface Vehicle (USV) followed by Saildrone Explorer, Saildrone USV, or saildrone for simplification, with Saildrone (capitalized) reserved for the company.
